GeForce 920M		14400 MB/sec
	Difference: 59200 (411%)

Texel Rate

The GeForce 920M is much (about 21%) better at AF than the Radeon HD 5750 1GB. (explain)

GeForce 920M		30528 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 5328 (21%)

Pixel Rate

The Radeon HD 5750 1GB will be much (more or less 47%) better at FSAA than the GeForce 920M, and also will be able to handle higher screen resolutions better. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 3568 (47%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
